GBA - Proof of Concept

What it does

Generative Based Authentication (GBA) is an innovative authentication method developed by 4DA. This app is just a proof of concept and the emphasis is on the sign-in phase.
Here’s how it works:
Sign-Up Process:
Email Link: The user receives an email containing a link to a story generator powered by a Large Language Model (LLM), such as GPT.
Story Creation: The user generates a story of their choice using the provided generator.
Story Approval: Once the user is satisfied with the story, it is saved, completing the sign-up process.
Sign-In Process:
Email Submission: To sign in, the user provides their registered email address.
Story-Based Question: The system presents a question based on the unique story generated during sign-up.
Authentication: If the user correctly answers the question, access is granted. If not, access is denied.
Additional Features:
Story Modification: Users can change their story at any time, along with the way questions are generated and answered.
Web-Based Convenience: The entire process is web-based, eliminating the need for any extra app installations.
Device Compatibility: Unlike many authentication apps like BankID, which require modern smart devices and may no longer work on older devices, GBA only requires access to a web browser, ensuring broader compatibility and accessibility.
